36 *
37 * void _exit(int status)
38 * void _Exit(int status)   -- added for SUSv3 standard
39 *
40 * code is return in r0 to system
41 * Same as plain exit, for user who want to define their own exit.
42 *
43 * _Exit() has been implemented as a weak symbol of _exit().
44 * This is the cheapest way to get a duplicate symbol of _exit()
45 * which is all that is required.  To the dynamic linker there
46 * is no difference between a strong and weak symbol.
